To all whom t may concern: f

Be it known that we, HARRY A. ORLorr and `:DavID BAKER SMITH, of .Venice and Los Angeles,'respectively, in the county of Los Angeles and State of California, have jointly invented new and usefullmprove mentsin Concrete-Form Ties and Spacers (#4), ofrwhichthe following is a detailed specification. f Y

This invention relates to ties and spacersfor concrete. or klike forms; and provides..

a simpleform of'devioe that may bei' placed in engagement with opposite form boards or plates or .the like to hold them in proper spaced lrelation for any desired thickness of poured'concrete 'walls or other structure. The invention described in this application is somewhat similar' to, and ,involves certain developments and improvements upon the tie and spacer thatV is set outin ourU. Sv. Patent No. 1,468,790, dated September 25th, 1923, and in our. co-pending l application Serial No. 651,813, fi1edJuly 16th, Y1923, now Patent No. 1,491,413. The improvements and developments of the present invention will be mostv readilyunderstood from a consideration ofthe following detailed specification; but it maybe stated as a general object of the present invention to provide a tie and spacer that is strong and rigid, yet simple and inexpensive in construction. Like the structures of the prior patentand application, the present form of device is easily applied, saving greatly in labor 'and' time required for erection ofV forms.

VFor the purposeof exemplifying thehin-A vention, we will describe in the :following detailed description preferred and specific forms of this invention; and for this pur- `pose we refer to the :accompanying drawings, in which: Y t

Fig. 1 is a perspective showing one `form of our-device;

' Fig. 2 is an end view of the same ;v

Fig-3 is a side elevation` of same;

Fig. 4 is'small section indicating how the deviceis applied -to a form;n

Fig.V 5 is a'perspect-ive of another formof ldevice; jf. Y

` Fig. 6 is an end view showing a modication of thestructure of Fig. 5 ;V 1

Fig. 7! is an -end view showin another rmodiflcation of thestructure of Fig. -8 5 Fig. 8 Ais' a perspective illustrating another form of device;

aus

Fig. 9 is a 'side elevation of the forml j shown in Fig. 8.

Referring now firstto the form shown in l Figs. 1, 2, and 3, wemaysay that this form,

may be economically made of 'sheet' metal,"

bent up tothe,v proper shape;l and' likewise the lother forms of the; device which are illustrated. But `this is not necessarily .a

limitation upon the present invention, as

it willbereadily understood that these def vices may be "formed votherwise 'than1 from sheet metal, as' for instance of cast' metal'. However, `for the purpose of the specifica-VV tions, we will assume 'that the devices are made of sheetmetal, Vas that method of formation is the most practical one of which we know. Y

In the device of the formv shown inFig. 1,l

a metalsheet of suitable thickness is bent or formed so that its section issubstantially in the form of a W; and then'the edge parts of the piece are turned inwardly toform parts 10, that closethe bottoms ofthe outermost hollow ridges 11. The inneredgesof the parts 10,1nay be left unconnected with the walls of thelower ridge 12; or they mayv These partsV 10 are formed `to lie in thesame plane-fa central longitudinal horizontal plane from r,which the upperridges 11 probe electrically .welded or otherwise suitably- Y secured to the walls of the lowerrid'ge1-2.

ject upwardlyto thesame extent that the lower ridge 12'proj'ects downwardly g' and it is theseparts 10that formfwhat we may term a flat plate orv platesthat liebetweeii a the adjacent or abutting edges of form boards when the edges ofthe boards 13, or

plates or the like,'are'tak en in notches I14 and15V ofthe several ridges. j It will'be understood that, for clarityof description, we aredescribing the device as it appears in' Fig. 1; but it will be understood at the Y.

Sametime thatthefdevi'ce willl operatejust f as well in a position` turned, upside down fromfthe position shown in Fig. 1,!01 in any other position. j Likewise it will be vunderreferv ,to anything. of like nature, such as plates, thatmay be usedto form the'confinustood that ,whenV we refer to formboards we j i .Detalles tiene .15 formed. in esasperati@ plate 10, sothatY the adjacent edges of the boards are only spaced` apart by the thick- Y ness of plate 1 0. And of course, it will be obvious that, if desired, the boards inay be slightly notched where the plates are applied, so that their edges may then come into close abutment with each other. In practice, however, we find that it is unrnecessary in a great niany instances to notch the boards, as the plates 10 are so thinthat the boardedges are closev enough together even when spaced by the thickness Vof the plate.

= lridges .by brating,

vlhrough the top-:ot the ridgesA 11 and 12, weprovide o`penings20 and21 to receive or pass.reinforcing,rods.v The rods maybe placed 'vertically or horizontally through these openi ngs,as will be'ap-parent;4 and to passvertircal rods through the openings 20,

t-heplates 10, also, have openings as shown at 22.-'

InY Fig. 5 we show a forni that embodies two ridges, an upper ridge 11@ and lower ridge 12a, witha `central horizontal plate closing the bottoms of the ridges; or, the structure hereV may -be looked at as being substantiallyjof hollow diamond cross section with the plate` 10 `forming a diago; nal. VThe plate -inthis structure Inayfbe secured. atfits longitudinal Vedges to. the V electric welding, or by any'other suitable. means. The notches 14 and lreach, downto the oppositesurfaces of plate. lOaas ,before described; and the reinforcing rod Openings and 2l., and epi-:rings 221m plate.. 1.0v are provided as hereinbefore described. This structure, like/that; shownin 1 in akes a very *strong and. rigid device; strong as well against tension due te internal Concrete pressure as. against Compression, 'clue to any .forces t'efndingtoI 'force the opposite forni Y boards: towards each other.

' therefore t0. increase itsy strength.- Such an riveting or brazing or welding ln Fig'G we illustrate another inode of niakinglthe,.fo,rm shown in Fig; 5. `Here eachv ridge, 11 and 122, has its own in- Y dividual flat closure plate 10";V and the Ytwo plates. `may, then be securedv together'vv by l l i f the 'two plates 1,0b together.l j

In` Fig.. 7 we' show another inodiiication of` the orrn shown ini Fig'- 5. Here the plate 10a has lateral' extensions 10c that serve to increase the width of the plate and ncreasekn strength of yplate may be perticularly desirable `where the devices are onV high wall fornis wherev the concrete pressureat. thebottoin of thewall is very great.

inthe 'form shown in. Fig. l., the Strength "of plate 10 may .be increased by having rein- `tudinally forcing rod openings only in the ridge 12, or by utilizing the opening 2O in ridgesll only notches to take horizontal reinforcing. rods, thereby eliminating the openings 22 in plate 10. i I

ln Figs. 8 and 9v wel illustrate another inodii'ication, being a :torin that is sub-v stantially a `duplication of the foi-1n of Fig. Here the plate 10d is shown as eX- tending across two sections of ridge forniations 11a and 12a and is also, shown with. lateral extensions. 10C, as; Fig. T.' torni of device, as will be .readily recognized, is exceptionally'strong and rigid..

'Having described a preferred vforrnoi our invention, we claim:v s f 1. A tie for concrete or like forms, einbodyi'ng a fiat metalv plate and longitudi nally extending'rid'ges arranged at opposite sides of the plate and synnnetricallywith respect to a longitudinal central 4plane at right angles to the plane of the plate, said ridges having forni board receiving notches.
